Restore / Add Mesa With H.264, H.265 & VC-1 Decoding Support to Fedora 37

Add the RPM Fusion repos (if not installed yet)

sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm

The nonfree repository is not required for this spssifc use case, but add it as well if you don’t have it.

sudo dnf install https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

Then install mesa-va-drivers-freeworld and mesa-vdpau-drivers-freeworld:

sudo dnf install mesa-va-drivers-freeworld mesa-vdpau-drivers-freeworld

If mesa-va-drivers or mesa-vdpau-drivers is already installed:

sudo dnf swap --enablerepo=rpmfusion-free-updates-testing mesa-va-drivers mesa-va-drivers-freeworld
sudo dnf swap --enablerepo=rpmfusion-free-updates-testing mesa-vdpau-drivers mesa-vdpau-drivers-freeworld
